How to hide system error messages.

Hi,

I am writing a file system minifilter driver.
When I fail the create file operation from preoperation callback
routine, a windows error message pops up saying "file is not a valid
win32 application". and it restricts file from opening successfully.

But I want that no popup should be displayed on successfully blocking
a file. How can I hide this system popup?
Can anybody help me?

Thanks in advance.

Try:


{
DWORD oldErrorMode = SetErrorMode(SEM_FAILCRITICALERRORS);

<Your code>

SetErrorMode(oldErrorMode);
}

Thanks dataman,
But this wont do because I havent wrote user mode code.
Its system code.
For example i wanted to block the notepad.exe file to open so I fail
its creation in minifilter driver.
That action displays system error message. I wanted to hide this error
message.

Reply me if you need more clarification.

Choose another error code for failure, and note - even this will give you
no guarantees - it's the app's will on whether to show the popup or not, not
your driver's will.

Why? This is strictly an application decision. If an application gets an
error while creating a file, then it clearly is not going to be able to
provide the services that the user expects, and it is entirely appropriate
for it to display an error message.

What do you expect notepad to do?
